Common materials include canvas, PVC (polyvinyl chloride), plastic, polyurethane, and 100% recycled polyester.
Common closures are zippers and latch locks; some designs are open-top with no fastener.
Some spa bags are described as waterproof or water-resistant. Bags made from PVC or other durable plastics are easier to wipe clean and tend to be dustproof and water-resistant; clear designs also prioritize wipe-clean maintenance.
Carrying options include adjustable shoulder straps, double handles or portable handle straps, built-in hanging hooks, and back panels that can attach to a trolley case for rolling luggage.
Clear spa bags make contents instantly visible for quick organization and easier cleaning. Some clear travel bags are also sized and described as fitting stadium or event purse guidelines.
Common features include small elastic pockets and fixing straps, Velcro pockets, transparent zip pockets, divided trays, removable partitions, and auto-open trays with flip lids and mirrors for sorting small items.
